By the end of the first year, your baby has developed his own personality. Your baby is a full-fledged member of your family. It’s hard to imagine what life was like without him! In the months ahead look forward to your child doing the following. Sleeping about 12 hours at night, and getting up early in the morning. Needing a longer nap on some days and a shorter nap time on others, usually wanting attention when waking up. Many children will have a varied appetite, especially while teething. After 12 months, children grow more slowly and eat a little less. You may also find that your baby will have a language “explosion” at around 12 months of age. However, a 12 month old may only speak two or three words at a time.
